Great to hear Chipchopper :o)
We planted a Buddleia last year and have seen some wonderful butterflies this summer so far - It is literally packed full of them, so I've bought a couple of small buddleia's to plant ready for next summer as we've been so impressed with their effect. We hardly saw any at all last year and love watching them.
After 3 years, the one and only remaining Echium Pininana (the others perished in the frost) flowered and the bees went crazy for it! I'd recommend one if you like the bee's, although they do take a while to grow and are rather large! :-)
